Abstract: A chamber in a valve case has an inlet port of exhaled air in one of its end walls. Spaced inwardly from the side wall of the chamber is a valve seat surrounding the inlet port and engaged by one side of a sealing member, the opposite side of which is engaged by a rigid disc secured to a valve stem that extends through the port and into guiding means for the stem. The diameter of the disc is nearly as great as the diameter of the chamber. A spring in the case is compressed between the disc and the other end wall of the valve chamber for pressing the sealing member against the seat. The disc is spaced from the ported wall of the chamber far enough for the marginal portion of the disc that extends laterally out beyond the sealing member to be inclined toward the ported wall but spaced from it. The side wall of the chamber is provided with exhaust slots extending around the disc and having inner walls adjacent the ported wall lying in a plane substantially coinciding with the plane in which lies the edge of the disc, and the space between the valve seat and the side wall of the case is always open to the slots.

Abstract: A processor is disclosed having improved circuitry for (1) generating m+n-bit address words from n-bit data words and (2) converting m+n-bit address words back into data words having an n-bit format. The processor includes a first arithmetic unit (AMU) that is n bits wide and which receives n-bit words from a data bus. The processor further includes a second AMU that is m bits wide and which is connected to receive the m least significant bits of an n-bit word stored in the first AMU. An m+n-bit address word is formed by (1) applying a first n-bit word from a system data bus to the first AMU with the m most significant bits of the address word to be formed being contained in the m least significant bit positions of the first word, (2) transferring the m least significant bits from the first AMU to the second AMU and concurrently applying from the data bus to the first AMU a second n-bit word representing the n least significant bits of the address word, and (3) concurrently reading out both AMUs to apply an m+n-bit address word to a system address bus. This procedure is reversed to convert an m+n-bit address word into n-bit data words.

Abstract: The invention concerns an arrangement for increasing the fire resistance for a fire-protecting lead-through of cables in walls or the like and is based on a known technique, whereby the cables are led each through their own piece of packing of elastic material, which when heated expands to such a volume that the cavities formed from the parts of the cables which are disrupted by fire are filled by the expanded material. According to the invention, each cable 1 is surrounded by a body 2, consisting of a non-flammable or fire-retardant, elastic, bending-deformable material, wherein the body is situated at one end close to the piece of packing belonging to the cable. <IMAGE>

Abstract: A relatively high-power switching device and circuit includes a first VMOS transistor which is turned on for supplying via its channel a first current to the base electrode of a bipolar transistor, for turning on the latter into at least an unsaturated conduction state, thereafter a second VMOS transistor is turned on for supplying a second current concurrently with the first current to the base electrode of the bipolar transistor, causing the latter to go into or close to saturation as possible, depending upon the characterstics of the load, for minimizing the power dissipation thereof during a major period of its conductive state. The second VMOS transistor has its channel connected between the base and emitter electrodes of the bipolar transistor, whereby when the former is conductive, in addition to supplying the second current, it also provides negative feedback between the collector and base electrodes of the bipolar transistor, thereby enhancing the transient capability of the bipolar transistor. The bipolar transistor is turned off by first turning off the first VMOS transistor, ensuring the former is placed into a non-saturated conduction state, and thereafter the second VMOS transistor is turned off, reducing the base current to zero, causing the bipolar transistor to turn off. In this manner the turn-on and turn-off times for the bipolar transistor can be minimized.

Abstract: An object is manufactured from a powdered material by isostatic pressing of a body, preformed from the powdered material, with a pressure medium, whereby the preformed body, in which at least the surface layer consists of a ceramic material in the form of a nitride, is surrounded by a casing which is rendered impenetrable to the pressure medium, before the isostatic pressing is carried out and the powder sintered. As the material in the casing there is used boron oxide or a glass containing boron oxide or a material forming glass while being heated, in which the content of boron oxide is sufficiently high for the glass-or the glass formed during heating-to be removable by water. The preformed body surrounded by the casing is subjected to a heat treatment for the formation of boron nitride on the surface of the preformed body, before the isostatic pressing is carried out. The casing is removed from the finished product by means of water or water vapor.

Abstract: A boiling water nuclear power reactor includes an improved control rod associated with each of its clusters of fuel assemblies. The control rod has an elongated central stem defining a longitudinally extending internal central gas plenum and a plurality of blades orthogonally arranged in pairs to provide a cruciform configuration in which the blades connect to and extend radially outward from the central stem. Each blade incorporates a series of internal cavities arranged in columns and rows across the length and width of the blade, and a neutron absorbing pellet is disposed in each cavity. The cavities communicate with the central plenum so that any gases generated by irradiation of the pellets can expand into the plenum. The cavities and pellets are arranged to form a longer, constant worth section in a body portion of each blade and a shorter, reduced worth section in an end tip portion of each blade. The end tip portion leads insertion of the blade body within the space between adjacent fuel assemblies when the control rod is moved into the fuel assemblies to control the reactive power thereof.
